WebTrigonometry. Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle', and μέτρον (métron) 'measure') is a branch of mathematics concerned with relationships between angles and ratios of lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. graber blind string replacement

WebApr 23, 2015 · When you take the corresponding angle in the 2nd quadrant, you have 3pi/4, which also gets you sqrt (2)/2. Now the final step: flip the angle across the 2nd quadrant into the 3rd quadrant – you get 5pi/4 ! But since we are in the 3rd quadrant, now, sin is negative. THEREFORE, sin (5pi/4)=-sqrt (2). Put all the numbers back where they belong ... WebNov 4, 2015 · #csc ((5pi)/4) = 1/(sin) = -sqrt2# Answer link. Related questions. How do you find the trigonometric functions of any angle?
